Abstract

This paper proposes a method in which to formally specify the design and reliability criteria of an advisory system for use within mission-critical contexts. This is motivated by increasing demands from industry to employ automated decision-support tools capable of operating as highly reliable applications under strict conditions. The proposed method applies the user requirements and design concept of the advisory system to define an abstract architecture. A Markov reliability model and real-time scheduling model are used to effectively capture the operational constraints of the system and are incorporated to the abstract architectural design to define an architectural model. These constraints describe component relationships, data flow and dependencies and execution deadlines of each component. This model is then expressed and proven using SPARK. It was found that the approach useful in simplifying the design process for reliable advisory systems, as well as effectively providing a good basis of a formal specification.
